SPECIFICATION forming part of Letters Patent No. 757,509, dated April 19, 1904.

Application iiled June 15, 1903.

T0v or/ZZ whom, it may concern:

Be it known that I, "WILLIAM M. SCOTT, a citizen of the United States, residing at Saxton,

in the county of Bedford and State of Pennsylvania, have invented or discovered new and useful Improvements in Retort Coke-Ovens, of which the following is a specication.

In the accompanying drawings, which make part of this specification, Figure I is a vertical longitudinal section through one of the retort-ovens; Fig. II, a vertical section on the line II II of Fig. I; Fig. III, a horizontal section on the line III III of Fig. II; Fig. IV, Aa horizontal section on the line IV IV of Fig. II, and Fig. V a horizontal section on the line V V of Fig. I.

My invention relates to retort coke-ovens having tilting or pivoted bottoms, and more particularly to the means employed for operating the bottoms and to the structure of a battery of ovens'v adapted for use with thef oven-bottom-operating means. -Its object is to provide a coke-oven battery with a vbottomoperating mechanism which can be transferred to an operative position with respect to each bottom and can be' readily attached tok and detached from the same.

Referring now to the drawings, 1 desig-k nates the supporting walls or foundationsv which run transversely of the oven-battery,

but longitudinally under. the walls 2 of the oven-chambers 3. A number of these chamcoked is charged. 'Ihe materialis broughty opposite the charging-holes 4 by means of cars, (not shown,) which run on the traclf'l, extending longitudinally of the battery of ovens and between the rows of the chargingholes. The ends of the ovens or chambers 3 have hinged doors 6, in each of which, nearV the top thereof, is a small hinged door 7 At each side of the battery is a track or rail 8, on which the wheel 9 of a hanging platform 10 travels. This platform has on its under side Serial No. 161,418. (No model.)

a wide wheel 11, which* runs on a track consisting of a series of ribs 12, carried by the oven-walls 2, and of the ribs 13, carried by the doors 6, the ribs 12 being slightly below the ribs 13 to permit the' former to pass the latter when the doors 6 are opened. The wheel 11 is wide enough to run on both series of ribs. The ovens 3 have a series of exit-ports 14 for the escape of the gases evolved during the coking operation. The exit-ports 14 lead by way of short horizontal iiues 15 downwardly into vertical flues 16 in the walls 2. Opposite the bottomof the oven the lines 16 connect with horizontal flues 17, which run through the oven-bottom transversely and connect at the center of the wall 2 opposite the wall 2 in which the iiues 16 are with the uptake-fines 18, which open at their tops just above the top line of the oven-chambers into the transverse fines 19, which are crossed centrally by the longitudinal offtake-iiue 20, which conveys the spent gases to a chimney or other place. (Not shown.)

21 represents fines at the bottoms of the "walls 2, which connect with the iiues 18, as shown in Fig. II, and supply the requisite quantity of air to the evolved gases for their combustion.- Air is admitted to the iiues 21 by the sliding doors 22 or by any well-known way.

It will be noted that the gases pass out on the same' side of all the ovens and around the two sides and the bottom of each oven in the same direction-that is, in Figs. II and IV the gases move to the left in the oven-bottoms and in Fig. III` toward the top of the sheet. It will also be noted that the downtake-ues 16 of one'oven lie in the samewall 2 as the uptake-fines 18 of the adjoining oven. fines v16 and 18 in each wall 2stand in a straight `line and alternate, the 'vflues 16 .communicat- 'ing' immediately with lines 18 in wall 2 on one The f but are ready to be used when an additional oven is placed at the bottom of Fig. III or at the right of Figs. II and IV.

rIhe bottom 23 of each oven or chamber 3 is composed of two sections 24 and 25, hinged together near the middle on the pivot or hingepin 26 and containing the middle portion of the iiue 17. The section 24 is pivoted on the Xed pivot or pin 27, while the section 25 is supported centrally transversely on wheels 28 on tracks 29, consisting of the upturned flanges of plates 30, held between the walls 1 and 2, as shown in Fig. II.

Pivotally secured to and between pendent lugs 31 on the section 24 is the piston-rod 32, secured to a piston (not shown) in the cylinder 33, pivoted at 34 between vertical ears 35, centrally placed on a beam 36, swiveled at its center on a vertical pin 37, secured in the center of the platform or body 38 of the car 39. The car is shown mounted on the springs 40 and having wheels 41 on the track 42 lying at the bases of archways 43, extending through the supporting-walls 1 from one side of the battery to the other. The sides of the archways are provided with horizontal recesses 44, into which the ends of the beam 36 may enter when the car 39 is centrally between two consecutive walls 1, the shoulders of the recesses sustaining the reaction of the oven-bottom-operating means. The recesses show only one way of providing shoulders for the beam.

Between the walls 1 of the several ovens are the two downwardly and outwardly inclined chutes 45 and 46, with which the free ends of the sections 24 and 25 register when the bottom 23 is in the position shown in dotted lines.

The bottom sections may be operated by other means or by the same means arranged differently, and other parts of the oven may be changed and still come within the scope of my invention.

The operation is as follows: Coal is charged through the holes 4 and leveled by a man standing on a platform 10 opposite each door 7, through which he operates a leveling-tool. rIhe gases driven off from the coal pass out of the ovens 3 through the ports 14, flues 15, 16, 17, and 18, where they receive a supplyof air from the iiues 21. The burning gas passes up iue 18 into the common iiues 19, and thence into the main offtake-flue 20 and the chimney. (Not shown.) If desired, the air can be admitted through the small doors 7, so as to partially supply the gases with oxygen before they pass into the flues 18. When the coking is completed, the doors 6 are opened and the car 39 is run to a central position nnder the oven-bottom 23. The beam is swung into diagonally opposite recesses 44 in the walls 1, as shown on Fig. V. The piston-rod 32 is connected to the lugs 31, and the piston- Iod is forced up in an obvious manner, causing the sections 24 and 25 of the oven-bottom 23 to become flexed upwardly at its center, as shown in dotted lines in Fig. I. This lifts the cake of coke near its central portion, leaving its end portions unsupported. The weight of the end portions causes the cake to break at the center, one end of the cake going down chute 45 and the other down chute 46. The flexing of the bottom 23 causes the wheels 28 to travel on the tracks 29 to the position shown in dotted lines on Fig. The vertical downward thrust of the lower end of the cylinder is not transmitted to an appreciable degree to the car, but to the lower shoulders of the recesses 44, and the upward lift of the cylinder when closing the bottoms 23 does not raise or tend to raise the car, but is borne by the upper shoulders ofthe recesses 44. As soon as the coke has been discharged a reverse movement of the pistonrod 32 restores the bottom to its normal horizonf tal position. rIhe doors 6 are then closed and the oven is ready to be charged again preliminarily to another coking operation. The piston is then detached from the lugs 31, the beam swung out of the recesses 44, and the car run beneath another oven and the operation repeated.

By using a single cylinder and making it transportable I save a large item in the cost of constructing and maintaining a coking plant in comparison with any method employing a separate cylinder for each oven-bottom or in comparison with the methods heretofore known.

It is obvious that my invention is adapted for the by-product process by simplyconducting off the expelled gases and admitting the purified gases into the iiues 16, ports 14 being bricked up. i Y

.I have not shown any pipes connected to the cylinder for the transmission of the motor fluid, as the showing of the cylinder is a conventional representation merely.

Having described my invention, I claim- 1. In a retort coke-oven plant, a battery of coke-ovens having pivotally-mounted bottoms, and transportable means adapted to be loperatively connected to any selected bottom for swinging the same on its pivotal mounting.

2. In a retort coke-oven plant, a battery of coke-ovens having pivotally-mounted bottoms, a car arranged to travel beneath said bottoms, and means mounted on the car and adapted to be operatively connected to any selected bottom for swinging the same on its pivotal mounting.
